To all whom, wmp/.concern- Be it known that I, WILLIAM CLIFFORD MAYNARD, Va citizen` of theUited States, residing at Miami, in the county ofpDade and State of Florida. have made certain new and useful Improvements in Pin Retainers, of which the following is a specification. l

My invention is a device adapted for application to a scarf or hat pin for preventing its ro accidental or surreptitious detachment.

rllne details of construction, attachment, and operation of In after ascribed, an illustrated in the accompanying drawings, in which Flgure lis a perspective view illustrating the application ofmy preferred form of the invention to a scarf-pin. Fig. 2 is a side view of the same parts. Fig. 3 is a perspective view of the retainer in the positionvrequired ae for adjusting it on the pin. Fig. 4 is a erspring which is so curved as .to have practi .cally the form of a hook. One end a of said spring is provided with an opening which is 5e adapted to receive-the bodyl or shank of the in somewhat loosely, so that when the adiacent portion a is inclined vor placed at an angle to the pin, as shown in Figs. 1,2, and 3, it will gripthe same by reason of the engagement of op osite edges of the opening with opposite si es/of the pin, yet when the part A" is adjusted at right angles, or nearly so, to the pin, as shown in Fig. 3, the retainer will slide freelyfon the pin, so that it may be adjusted higher or lower on the pin or detached, as occasion may re uire. The opposite end a2 of the pin is provi ed-wth a notch adapted to receive the pin as'indicated in Figs. 1 and 2. Thus when the end a2 is applied to the pin the portion a having the opening therein is forced downward at an inclination to the pin, and therefore grips the same or takes a iirm frictional hold thereon. As will be seen by comparison of Figs. 1 and 2 with Fig. 3, the angle of the part ato the pin depends to a certain extent upon the tension and leverage applied by the upper portion a of the retainer. In other words, when the end a is engaged with the pin the entire spring A is ut under tension and the part a' is thrown own to its greatest angle to the invention are as herein end provided with the openinv` pin, so that the latter'is firmly gripped. It will be seen that this tension becomes greater and the grip firmer when the end a2 ofthe re tainer is pressed downward, which ,pressure may be applied bythe material of the scarf or other part to which the pin is applied, and

such. pressure would obviously be applied if it were sought to remove the pin. Hence the retainer A will keep its place onthe pin under all conditions so long as the end a2 re.-

mains 'engaged therewith, and the notchv formed' in said end is in any case deep enough to receive the body of the pin and to retain. its engagement therewith, owing to the elasl ticity of the spring A as a whole.

It will be apparent that the efciencyiof my device depends largely upon the angle which the part a is adapted to normally/assume with reference to the pin. In. other words, if the part a were horizontalinstead of normally inclined to the -pin there would be 'no efficient gri ping action. .The upward bend of the hoo of the retainer is therefore Y an elenent'that promotes its eflciency.

In order to apply the retainer to a in or remove it therefrom, the notched en c? is held disengaged or free from the pin and the thepin, as willbe understoodloy reference to Fig. 3, and when the retainer has been adjusted to the desired position the notched end a2 is placed in engagement with the pin,

a is slid upon f whereby the' retainer as a whole is put under tension.

In Fig. 5 I illustrate ftmodnication, consisting of a plate A', which is provided withV an openin adapted to receive the pin a, so that the p ate will slide upon and grip the pin in the same manner as the retainer A, before described. To the free end of said plate A', I attach a spring a4, preferablya spiral spring, the lower end of which is connected with a tapered ca a5, adapted to receive the point of a pin. e operation is obvious.

In Fig. 6 I illustrate a spring-plate A2, hav ing the end a, in which the pin-hole is formed, made of double thickness or pro vided with a reinforce, by which chan e' it is apparent the pin-hole may be made s 'gntly larger than is practicable when the spring is made of uniform thickness throughout, since the edges that eng 'e and bite the are separated more Wide y, and hence the s ring may be used on ins varying greatly in t 'ckns, while its e asticity remains practically the same.

Having thus described my invention, what I claim as new, and desire to secure by Letmally at an angle to the pin so as to grip it in the manner described.

3. A pin-retainer consisting of a curved spring having at one end an opening adapted to receive a pin loosely, and its opposite end also adapted to engage the vpin and press against the same, so as to exert leverage upon the first-named end and thus hold it normally inclined to the pin, substantially as described. V

4. A pin-retainer consisting of a spring having ahook form, one end being provided with an opening adapted to receive a pin loosely, and the opposite end adapted to engage the pin, whereby leverage is applied to the end4 provided with 'the opening so that the pin is gripped and held by friction, substantially as described.

5. .A pin-retainer consisting of a s ring )which is in curved form, one end thereo havmg an opening adapted to receive a pin loosely, and the opposite end provided with av notch also adapted to receive the pin, the

si 1,421 r construction being such that when the notched end of lthe retainer is engaged With the pin the opposite end is held at an inclina tion tothe pin and thereb)T caused to grip the same in the manner described.

- 6. A' pin retainer consisting of a spring having a hook form, the shorter arm or member of such hook having an opening adapted to receive a pin loosely and the opposite end being adapted for engagement with the pin, the construction and arrangement being as described, whereby when the upper endof the springgi's applied to the pin, the shorter armor member is thrown downward and held at an inclination to the pin, the tension and leverage of the spring bein thus proportionate to the pressure applied y or to the upper portion of the spring, substantially as described.

7. As an improved article of manufacture,

a pin-retainer consisting of a spring having hook form, one end being provided` with an opening'adapted to receive a pin loosely, and the opposite end provided With a notch for engaging a pin, substantially as described.

8. The'imp'roved pini-retainer, consistingl of a plate-spring which is in curved form, one end being provided With an opening adapted to receive a pin# and thevopposite end also adapted tovengage the pin, the angle of the part having the opening being such that it is held at an inclination tothe pin When the other end is applied thereto, substantially as described.
